It makes sense that it is less exciting to have a new roof installed on your home than to remodel your kitchen or bathroom, but if you own a home, you will have to replace your roof at some point.

Given the time and expense of roofing systems, the job must be done the first time correctly.

You’ll only have to spend more time and money later down the line if it’s not.

Unfortunately, our team at GreatWay Roofing has encountered common roofing mistakes that other roofers have made to cut corners. And when it comes to your roof, even minor roofing mistakes or shortcuts can lead to long-term problems and, potentially, high-cost repairs for your property. We have outlined some of the most common roofing errors below, so you know what to be aware of the next time you have roofing work done on your home.

Placing New Shingles Over Existing Shingles

You may legally be allowed to place your new roof shingles over the existing shingles, but should you? It depends on a few factors, but the most critical is knowing if the original plywood or underlayment is damaged or needs replacing. Unfortunately, if the original shingles remain on the roof, there is no way to tell if the wood or underlayment is damaged. Therefore, it’s always best to start fresh by pulling the original shingles off the roof to inspect and replace any faulty plywood before installing new underlayment, followed by asphalt shingles or tile.

Keeping the Old Roof Flashing

A roof’s flashing plays an important role in redirecting water away from the roof and preventing other forms of damage. Unfortunately, some roofers will cut corners by leaving the old flashing, which may be bent or worn, causing potential big problems with water penetrating your roof or walls.

Poor Installation of Roof Flashing

The flashing must also be correctly installed to do its job properly. A reputable roofing contractor will take as much care with the installation of the flashing as they do the installation of the shingles. Some common flashing issues include misalignment, overlap, and fastening weakness.

Using an Incorrect Nail Length

Shingles (and tile) must be securely fastened in order to work correctly. There are various reasons shingles can loosen, tear or blow off, but one of the causes can be using an incorrect nail length during installation. If the nail doesn’t go deep into the roof’s decking, or if it is exposed to the elements, this can reduce the lifespan of your roof.

Exposing Roof Nails to the Elements

There are specific locations nails and fasteners should be placed when installing a new roof. For example, suppose a nail is placed in an area that leaves it exposed to the elements. Over time, the structural integrity of the nail will begin to erode, which in turn will compromise the structural integrity of the shingle and the roof as a whole.

Forgetting About Roofing Ventilation

Many homeowners are alert to the importance of insulating their homes. However, it’s also essential to consider ventilation, specifically in the attic. Without proper ventilation, your attic can become too hot and, over time, damage your roof. Lack of ventilation can also cause excess moisture, which can be problematic for your roof and home.

Failing to Obtain a Proper Permit

A permit is required in most cities in California to install a new roof. Pulling a permit for a new roof project ensures that the building codes are being followed. Failure to obtain a permit can lead to significant problems, including the suspension of work on your roof, no matter the stage of your project. Working with a reputable roofing company can ensure that you’re fully compliant before work begins.

Not Installing Drip Edge

A roof’s drip edge plays a crucial role in directing water away from the roof and, ultimately, your property. Without an adequate drip edge in place, there’s a higher probability that water can make its way under your shingles, especially during wind-driven rain, at which point it can cause damage to your property.

Neglecting to Install Underlayment

Adding an underlayment between the wooden deck and the shingles is vital to provide an effective waterproof or water-resistant seal to your roof. Not only does this help to keep moisture away from your property, but it will also prolong the life of your roof. Shingles or tiles alone do not provide the necessary waterproofing required to keep your home dry.

Misaligned Roof Shingles

Misaligned shingles are a telltale sign that a professional has not completed the roofing project. For one thing, misaligned shingles can compromise the aesthetic qualities of the roof, making it look uneven. More seriously, they can create gaps that allow water to seep through and damage the home.

Shingle Overhang Issues

Shingles should hang slightly over the roof’s edge to help prevent water seepage. However, it’s equally important not to position the shingles where they hang over too much since this increases the chance of high winds dislodging the shingle.
